WINDOW are Application filed June 10,

This invention relates to improvements in window shade stops.

The primary object of the invention re window casing approximately onthe same plane with the meeting lflllS' of the upper and lower sashes toprevent accidental raising of the shade beyond its usual half-wayposition, the said stops being engaged by the cross strip at the lowermarginal edge of the shade.

A further object is the provision of a shade stop through which thesideedges of the shade slide during the movement of the shade, and whichserves to guide the same during such movement.

A still further object is to provide a shade stop which is simple ofconstruction, inexpensive of manufacture and which can be applied towindow casings without marring or tending to detract from the appearancethereof.

With these and other objects in view, the invention resides in thecertain novel construction, combination and arrangement of parts, theessential features of which are hereinafter fully described, areparticular- 35 ly pointed out in the appended claims, and

are illustrated in the accompanying drawings, in which:

Figure 1 is a front elevational view of a window equipped with myimproved shade sto Figure 2 is an enlarged detail vertical sectionalview on the line 22 of Figure 1.

Figure 3 is a fragmentary vertical sectional view taken at right anglesto Figure 2.

Referring to the drawings by reference characters, the numeraldesignates a window casing of the conventional type which supports aspring actuated shade roller 11 at the top thereof, and on which theshade 12 is windable. It will be appreciated that 1930. Serial No.460,173.

ofttimes the shade will accidentally move up- -ward and wind about thespring roller 11,

and which idle rotation tends to reduce the spring tension ofthe rollerand which 'requires the removal of its roller from its bracket in orderto reset the tension. My invention-aims to prevent the accidental wind-"ing ofthe shade upon the roller and to guide the shade in its slidingmovement.

My improved shade stop is designated by the reference numeral 13, andincludes a disclike body 14 which maybe constructed of jwood orotherlike material. The body 14 centrally thereof is provided with an opening15 for the passage of a fastening element in the nature of a screw orthe like 16, whereby the shade stop may be fixedly attached to the innerside of the window casinglO.

Extending outwardly from one ofthe flat faces of the disc like body 14is an extension 7 portion 17 which is semi-circular in end elevation asbest seen in Figure 2 0f the drawings. The extension portion 17 isslotted inwardly as at 18 from its outer end and which slot terminatesat the adjacent flat face of the body 14.

In practice, my improved shade stops are used in pairs and arerespectively mounted on the same horizontal plane on opposite sides ofthe window casing 10. In the present in- 30 stance, these shade stopsare mounted on a plane substantially the same as the plane of themeeting rails of the upper and lower sashes of a window although theymay be mounted adjacent the top of the window cats ing as indicated indotted lines in F igure 1 of the drawings. After the shade stops havebeen attached to the window casing by passing the fastening elements 16through the openings 15 and screwing the same into the' so windowcasing, the opposite side edges of the shade 12 are flexed and insertedinto the slots 18. It will therefore be seen that the shade 12 may havefree vertical sliding movement, and be guided in its movement by thewalls of the slot 18, and the raising of the shade is limited by reasonof the fact that the cross strip at the lower marginal edge of the shaft12 and indicated at 19 abuts the under side of the respective stops. InFigure w; 1" g r 1,806,373 1 1 it will be noted that the shade cannotpass above the plane ofthe stop'which serves to prevent accidentalwinding oftheshade upon its roller. If for any reason it should bedejsired to fully wind the shade, the shade may be flexed to move theside edges out of the slotsof the respective stops and then permitted toWind up. The stop devices as before stated prevent the accidental idlewind- 10 ingrof the shade upon the roller to prevent the roller fromlosing its-spring tension, and the shade is guided by the walls of theslots 18.
